. ROLLER-SKATE.

fJPll CIFICATION l'orming part of Letters Patent No. 305,434, datedSeptember 23, 1884.

Application filed May 28, 1884. (No model.)

To all "whom it may concern:

Be it known that I, THOMAS H. DEAN, of Easton, in the county of Bristol,State of Massachusetts, have invented a certain new and usefulImprovement in Roller-Skates, of which the following is a. descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention. appertains to make and use thesame, reference being had to the accompanying drawings, forming a partof this specification, in which Figure 1 is a side elevation of myimproved skate; Fig.2,a vertical longitudinal section of the same, aportion of the body being represented as broken away. Fig. 3, a verticaltransverse section taken through the center of the forward axle Fig. 4,an isometrical perspective viewof the guard and roller carriagereversed; Fig, 5, an enlarged side elevation of one of the rollers ortrucks detached, and Fig. 6 a vertical transverse section of the same.

Likeletters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates to that class of rollerskates which are providedwith a pair of rollers at either end, and a spring interposed betweenthe axle of either pair of rollers andthe body of. the skate; and itconsists in a novel construction and arrangement of the parts, ashereinafter more fully set forth and claimed,

by which a more desirable and effective article of this character isproduced than is now in ordinary use. In nearly all skates of thischaracter much difiiculty is experienced,when they are used by ladies,inkeeping the oil with which the axles are lubricated from coming intocontact with their skirts, as well as properly lubricating the axles.The rollers or trucks are also usually composed of solid boxwood orsimilar materials, which are liable to slip on the floor in turning,wear unevenly, and produce a disagreeable noise.

To obviate these and other objections, simplify the construction, andincrease the utility of the skate is the design of my present invention,the nature and operation of which will be readily understood by allconversant with such matters from the following explanation.

In the drawings, A represents the body of the skate, B the heel-strap,and G the toeitrap, all of these parts being of the ordinaryconstruction, and not in and of themselves claimed broadly herein.

Secured to the under side of the forward end of the body A there are twodownwardlyproj ecting brackets, D E, a corresponding pair of bracketsbeing also secured to the body at the rear end or heel, as best seen inFig. 1. A carriage or guard, H, provided with a centrallydisposedoutwardly-projecting stud, w, on either side is j ournaled in each pairof the brackets D E, the studs projecting into sockets m formed in thebrackets, and by which the studs are also covered. The guard is dividedinto twochambers'or compartments by the transverse partition 2, and thetrucks J are journaled in the guard, one in each compartment,by meansofthe axle K,which passes through suitable holes, b, in the side wallsof the guard and partition 2:, and is provided at either end with acap-nut, 15. A11 elongated rubber cushion or spring, 1), is disposedbetween the top of each of the guards H and the bottom of the body A,these cushions being held in position byscrews 1. The body of each ofthe rollers or trucks is composed of annular leather plates, and thesides a of corresponding plates of green hide, the plates beingconnected by suitable rivets. (Not shown.)

A series of pockets, M, are formed in the body of each of the rollers,the pockets being filled with cotton waste or some other suitableabsorbent for the oil, and provided with ducts h which extend throughthe bushing or axlebox i to the axle K, the cotton being kept properlysaturated with the lubricant when the skate is in use. The plates ofleather and green hideform a very durable wheel, and one which runs withcomparatively little noise. The cotton in the pockets M being saturatedwith oil keeps the axles constantly and uniformly lubricated. The guardsextend nearly to the floor and effectually prevent the rollers frombeing brought into contact with the clothing of the person using theskates, or a that of others in the vicinity. The spring interposedbetween the guard and body of the skate permits the body of the skate tobe rocked or canted laterally on the pivots or studs in turning orskating on a curve. The axle-hole in the guard is squared in one of theheads of the guard, as shown at g in Fig. 4, and the axle -K has one ofits ends squared, as shown at n, Fig. 3, to fit said hole, therebypreventing the axle from turning in the guard and the nuts it fromworking loose.

I do not confine myself to constructing the rollers of leather and greenhide or providing them with pockets and ducts, as described, as

they may be. made of box-wood or other suitable material, and thepockets and duets omitted, if desired. Neither do I confine myself toconstructing the guard with the partition I foot-piece, means forattaching the body or foot-piece to the foot of the wearer, twodownwardly-projecting brackets at or near either end of the body orfoot-piece, a guard or carriage journaled in either pair of saidbrackets, a pair of trucks or rollers journaled in either of saidguards, and an elastic cushion or spring, the guards being adapted tocover all parts of the rollers except their lower or 9 bearing edges andto rock laterally in the brackets, the rollers journaled at right anglesto the axial line of the guard, and the spring interposed between theguard and body of the skate and adapted to keep the bodyin a horizontalposition, substantially as described.

2. In a roller-skate, the brackets D E, provided with the coveredsockets m, for. receiving the studs or journals of the carriage H,substantially as set forth.

3. In a roller-skate, the guard H, provided with the studs 00, incombination with the rollers J, axle K, brackets D E, and spring o,substantially as described.

4. The improved roller-skate herein described, the same consisting ofthe body or foot-pieee A, provided with the straps B O, the brackets DE, provided with the sockets m, the guard H, provided with the studs 00,partition z, and holes for receiving the axle, the axle K, provided withthe nuts t, the spring 12, provided with the screw Z, and the rollers J,composed of leather and green hide,

and provided with the pockets M and ducts l2, constructed, combined, andarranged to operate substantially as described.
